Using Tealium to integrate DFA and GAP

Which would be the process to integrate DFA in Google Analytics using Tealium? Is there any documentation on this matter?
We know that it can be done by adding a simple Javascript line to the GA tag, but as in this case, as Tealium manages the Tag, we need to know how to perform the same task through Tealium.
Additional information about this can be found here:

Any thought?
